Today we're going to take a look at the Curt GM OEM puck system fifth wheel roller adaptor rails. This is a custom fit part. It is designed to fit the 2016 and newer Chevrolet Silverado, and GMC Sierra 2500 and 3500 trucks that have the six and a half foot bed, and the factory rail kit installed. Now, on a custom fit part, I always like to recommend for you to go to our website, use our fit guide, put in your year and model vehicle, and it will show you if this will work on your vehicle. Now, this is a custom base, specifically designed to attach to the receivers in your Chevy or GMC factory installed under bed towing prep package. This base will work with the Curt hitches that have sliders, part number C16521, C16516, C16541, and C16536. All those part numbers we do sell separately on our website.
Now, the adaptor, when you do install this into the puck system, it does add about a 1 3/8 inch height compared to your industry standard rails. It does use the quarter turn anchoring system for a nice quick installation and removal. All you have to do is pop this pin and clip, that's tethered to the rail, open this a quarter of a turn, and you'll notice the tabs turn. You'll do that on all four corners, and that will allow you to drop this base right into the puck system in the truck. Once it drops in, just turn it a quarter of a turn to lock it into place. Take your pin and clip, and then just install that back in there to lock that into place, keep this from opening. Now, if you notice, right here, they do have adjustable anchors to help to eliminate any chucking between any legs in the under bed platform.
You can just tighten or loosen this nut right here, to adjust the anchors. It does have a nice durable carbide black powder coat finish on it, to help resist corrosion. Comes with the four hitch pins and clips to secure your slider hitch to the adaptor. Comes with a nice set of detailed instructions that describe how to put it all together. Again, the specs on this, it's for a 2016 and newer Chevy or GMC truck with the factory installed under bed towing prep package. It does have a weight capacity of 20,000 pounds.
Basically, once you open these quarter turned system right here, drop it into your puck system, close them up, lock them into place, and this is installed in your truck bed. Then you'll notice these slots right here, this is where your Curt slider hitch will drop right in, and then using the included pins and clips attach it to the adaptor. Simple as that. That should do it for the review on the Curt GM OEM puck system fifth wheel roller adaptor rails.

This adapter is specially designed to attach to the receivers in your Chevy/GMC's factory, underbed 5th-wheel towing prep package. The base then provides the attachment point for your Curt 5th-wheel slider or roller.Very heavy duty hitch. Initially had some concerns so ordered the 20,000 lbs. instead of the 16000. Very good service from the etrailer representatives. Had some concerns on how long the delivery was going to take, however they were able to get it to me in a very short time. Thank you to the individuals who helped with my order. Danny 338540
Vanessa N confirmed that this was the correct puc base for our fifth wheel hitch. The product arrived promptly. It was easy to assemble after viewing the handy video and everything fits perfect. It took only about 20 minutes to assemble. We always shop online at etrailer for our product needs as they provide the best customer service and are very knowledgeable. 612020
Does exactly what it's supposed to be doing great slider 603906
Awesome product. Fit right into my factory set up. Highly recommend!!! Natalie was awesome! 574593
Perfect fit to my factory set curt hitch 571147
Perfect fit to factory GM puck system. Very happy! 570757
Very easy to assemble. The instruction should say not the tighten the bolts on the crossmember until the base of the hitch in placed into the slots that attach the lower hitch to the rail assembly. I tighten all the bolts before I attempted to attached the lower hitch to the rails and the rail slots would not alleign with the base. Once I loosened the nuts the base fit perfectly then torqued all the nuts. 560335
Easy assembly and worked as described 522496
I ordered my Curt hitch/adapter rails from etrailer and received a great price and prompt delivery. Everything arrived in good shape and has worked to perfection. Thank you etrailer. 497381
After a two years my hitch has worked to perfection. Great product.
Philip - 04/15/2019Prefect, purchased one with one pin missing, which I had. Saved $100.00. Assembled it, installed it in 30 min. Very heavy duty unit, already recommended unit to a friend and would recommend it to anyone. 494620
Fit perfect in my 2018 GMC Denali. 491878
Very good product! Super easy to install. Took me less than 30 minutes to have my 5th wheel hitch set up and ready to pull. Only weighs 80lbs and is easy to take in and out of the bed of the truck. Shipping from etrailer was fast. This is my second purchase from etrailer. Great experience. Company very heart full. 465116
The C16023 worked perfectly with my new Chevrolet silverado LTZ 2500 HD under the bed mounted fith wheel attachment. The only thing I recommend is to read the instruction before installation. It looked so simple to install I went ahead without reading the instruction and had to use a hammer to close the last locking handle. As it turns out there is a simple Castle nut and cotter pin adjustment to make. Luckily I did no damage and all went well during the installation. I would highly recommend this product. Also etrailer.com was vary helpful over the phone helping me figure out what I needed for my truck.. They also emailed when package was shipped and when it was delivered. They have the best prices as well. A big thanks to there customer service team for all of there help. 465090
Perfect fit. 460886
Very simple to put together. Very heavy unit. Made sure that I forced the clamps closed going into my puck system (just for piece of mind!) 441410
fit perfect 421185
Installed Curt A20 hitch w/slider rails in 2016 Chevrolet Z71 2500 411361
Adapter plate is not only heavy but quality looks great and fit right in. Only had to adjust one locking cam a little too tight 405837
Can not believe the condition of all items as they were received from shipping carrier. Boxes torn apart, bolts and nuts all scattered. Even 5th wheel hitch had rubber on handle cut. Found nuts and bolts on ground next to where the shipping carrier had unloaded items. Luckily found all nuts and bolts after searching area where it was off loaded from shipping truck. Even the cross brace for the hitch roller was bent. After reading other reviews I kind of expected this however. I can't believe you would ship something like a hitch protecting in the cheap boxes used! You need to improve the packaging! Other than that it did arrive quickly. 396454
Fits great 394875
fit like a glove 392937
The product is great and if you put the puck rails together write the system goes together easy, my only complaint is with UPS my boxes where damaged badly and some of the bolts and one hitch pin was missing. I went to the local store and they had everything I needed so I was only out an extra $25.00 for the parts, considering I got the system for a lot of money and the dealers here wanted $2500.00 to $3000.00. 392250
As always etrailer was a pleasure to work with. The box was damaged during shipping and a bag of screw fell out. One call to Etrailer and the problem was solved. Took about 30 minutes to install. (Half of that was finding my torque wrench). 376027
Works as described and fit well in my 2016 Silverado 3500 after adjusting the castle nuts. Unfortunately, the extra height (over standard rails) is preventing me from getting the RV level. With the hitch bolts in the lowest holes, the hitch sits just over 19 inches. Even with the pin box at maximum height, the front of the RV rides high. Disappointed. 374952
Went together great fit excellent in the puck holes slider works great looks nice without having the rails to deal with fits nicely under the cover when not in use thanks 373091
I recently purchased a fifth wheel hitch for my new truck but wasn't sure I ordered the correct one after hitting the "enter" key! I called etrailer the following morning and found out I had, in fact, ordered the wrong hitch. The young man I spoke with was incredibly helpful - he canceled my initial order, explained what I really needed and why and then placed the order. I went on line the next day and found that the order had somehow been cancelled. I then spoke with LEAH G. She is the bomb. She corrected everything and did her best to expedite shipping including personally making certain that MY shipment was on the last truck of the day. What more can I say. Etrailer.com and Leah G are unbelievably awesome from beginning to end! Thank you for a great experience Conrad 369499
Everything is still working great!
Conrad C - 04/19/2018Purchase process was easy, came in a few days and fit the truck as promised with minimal effort. My Reese hitch fits perfectly in the adaptor. 355975
Fifth Wheel was awesome Strong heavy construction Easy to install Love it 353342
Product is just as described. Extremely well priced and amazingly fast shipment. Good communication and tracking. I will definitely purchase from etrailer.com again. 342554
This adapter for towing prep package on Chevrolet trucks was simple to assemble and install and I would recommend to anyone. For me, I did not mate a Curt hitch on the mount and consequently the design of the mount prevents my hitch's sliding feature from working (the slide can not be unlocked). The angle steel which is used to hold the two mounting point halves blocks one of the lock pins. I hardly ever used my slide so I am not concerned. 332651
